I removed the original electric head and holding tank system in the stateroom, and replaced it with a Sealand RV gravity dump model. It sits directly above a 30 gallon tank, and uses a pint or so of fresh water with each use. We have used gravity systems on boats we have chartered, and like the simplicity of it. The tank is angled aft and inboard to the pick-up fitting, to get the maximum removal at each pump out. I used PVC schedule 40 pipe for the pump out line, well supported but flexible. It finishes with a two foot length of hose to the deck plate fitting. So far, it has work fine. The First Mate lost a full size drawer in the bargain, but she's a good sport. I was able to give her a lower drawer that is 7 inches deep, so it wasn't a total loss. She laughed at it, and thought it was cute. She also got the 4 x 2 x 1.5 foot space the original holding tank came out of. It forms a settee between our bunks. When working under the berths, I was always finding air fresheners everywhere. When I removed the aluminum tank, I discovered the bottom full of holes, eroded away. The PO just tried to disguise the odor. Yuck!
